Occupational dermatoses in farmers growing okra (Hibiscus esculentus L.)

Abstract

By questionnaire survey, 32 out of 52 workers (61.5%) reported previous or current skin diseases from okra cultivation. The sites of skin lesions were mainly the arms, fingers and fingertips. Positive patch test reactions with preparations of okra leaves or immature pods in 111 workers, compared to 63 control subjects, were significantly higher in okra workers than in controls (p less than 0.01), ranging from 9.8 to 30.0%. 37 out of 111 workers (33.3%) were diagnosed as having allergic contact dermatitis (n = 17; 15.3%) and irritant contact dermatitis (n = 18; 16.2%) from okra cultivation.

Plant dermatitis: Asian perspective

“…Cases of occupational allergic contact dermatitis to tobacco leaves,[23] mitsuba ( Cryptotaemia japonica Makino) vegetable leaves and its stalks[24] and okra (or lady's fingers, Hibiscus esculentus ) leaves[25] have been reported in Japanese farm workers. Airborne contact dermatitis due to Japanese cedar pollen has recently been reported.…”

Type of Plant Architecture Can Conceal Fruit During Harvest of Okra

“…The secretion of exudates from all plant parts can cause skin inflammations (Matsushita et al, 1989). Due to the indeterminate growth habit of okra, harvests must occur at frequent intervals (preferably 2 or 3 times/week) throughout a period of approximately 4 months to ensure good quality, and acceptable returns (Akoroda, 1986;Iremiren et al, 1991).…”
